Valve Lash Clearance Adjustment for 2005 Toyota Land Cruiser?


NOTE
Measure valve clearance with the engine cold.

  1. Before servicing the vehicle, refer to the Precautions section.
  2. Drain the cooling system.
  3. Remove or disconnect the following:

    Negative battery cable
    Ignition coils
    Valve covers
  4. Set the engine to the top of the compression stroke with the valves closed for the cylinder to be measured.
  5. Check the valve clearance. The valve clearance specifications are as follows:

    Intake: 0.006-0.010 in. (0.15-0.25mm)
    Exhaust: 0.010-0.014 in. (0.25-0.35mm)
  6. Record the measurements for each valve.
  7. When all valve clearances have been measured, remove the camshafts.
  8. Remove the valve shims and measure them. Note this measurement along with the clearance measurement recorded earlier.
  9. Using the valve clearance and shim thickness measurements, find replacement shims in the Adjusting Shim Selection charts.
  10. Install or connect the following:

    Replacement valve shims
    Camshafts
    Valve covers
    Ignition coils
    Negative battery cable
  11. Fill the cooling system.
